DNA
Found in the nucleus of a cell and carry genes.
Chromosomes
The study of heredity
Genetics
What is homozygous recessive?
hh
An educated guess about the outcome of an experiment based on evidence that is testable.
Hypothesis
Segment of DNA on a chromosome the has inherited traits.
Gene
The physical appearance of a gene.
Phenotype
Give an example of a heterozygous genotype?
Bb or BW
When an experiment is done more than once by the same person.
Repetition
(Replication is the same trial done by someone else to compare results.)
In DNA the structure is referred to as a ___________________.
(Hint: Describes appearance.)
Double helix
The stronger of the two kinds of alleles
Dominant allele
The weaker of the two kinds of alleles
What is a recessive allele
Brown eyes, tall, blonde hair are all called a Genotype or Phenotype?
Phenotype
The type of data that is based on observable characteristics of things collected by the five senses.
Qualitative data
Father of modern genetics
Gregor Mendel

Tt
If the offspring are only tt? What are the genotypes of the parents?
tt
A factor of an experiment that is changed or manipulated in an experiment.
(Hint- Dry/ Mix)
Independent variable
What are the base pairs on DNA?
A-T or T-A
C-G or G-C
What are the possible phenotype % of two heterozygous parents?
75% Dominant
25% recessive
Cross a homozygous dominant genotype with a homozygous recessive genotype. What are the odds of getting a homozygous recessive?
0%
Gray eyes are a recessive trait. Cross a homozygous recessive mother and a heterozygous father. What are the odds of the child having gray eyes?
50%
Why do scientist use the Scientific Method?
To ensure their research is objective, reliable, and repeatable by providing a standardized approach to conducting experiments
